12 Claims. (Cl. 139--307) This invention comprises a novel and usefulribbon roller attachment for ribbon looms and more particularly relatesto an attachment which may be applied to conventional ribbon looms inorder to more compactly wind ribbons or other similar woven fabrics inside-by-side relation upon a beam.

The primary purpose of this invention is to provide an attachment and amethod whereby ribbons, Webbing or narrow fabrics after being woven uponconventional ribbon or narrow fabric looms may be rolled up in anydesired number in side-by-side relation upon a single beam or reel,thereby forming a firm, solid beam of ribbons.

A further important object of the invention is to provide a method andan attachment applicable to conventional ribbon looms whereby the numberof operations of handling the ribbons or woven fabrics between theweaving of the same and the dyeing operation may be greatly reduced; andwhereby a much longer length of ribbon may be efiiciently handled.

Yet another purpose of the invention is to provide a method and anattachment for conventional ribbon looms whereby a plurality of ribbonsmay be compactly wound in side-by-side relation upon a single beam,thereby enabling the beam and the ribbons wound thereon to be directlypositioned in a vat for pad dyeing or the like with a considerablereduction in the number of separate steps and operations of handling theribbon that have been heretofore required.

Yet another object of the invention is to provide an apparatus andmethod whereby a plurality of ribbons produced from a single ribbon loommay be simultaneously rolled upon a single beam with equal tension ofthe ribbons thereon, thereby enabling dyeing with even colors for all ofthe ribbons and enabling the operation of level dyeing to be more easilyperformed than with other methods involving variances in the tensions ofth ribbons.

Yet another object ofthe invention is to provide an attachment of aninterchangeable nature whereby the same loom may be adapted for windinga pluralityof different widths of ribbons in any selected number inside-by-side relation, under a constant tension and upon a same beam.

These together with other objects and advantages which will becomesubsequently apparent reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had'to the accompanying drawings forming a part hereof, whereinlike numerals refer to like parts throughout, and in which: T

Figure 10 is a diagrammatic view, taken upon an enlarged scale, of aportion of Figure 2 and showing an important feature and principle ofthe invention.

Referring first to Figure 1 of the drawings, it will be seen that thereis disclosed a conventional type of loom such as the well known Fletcherribbon loom, the same including a frame 10 supporting the breast beam12, the batten 14 with the shuttles 16. Indicated at 18 is the warp beamby which the warp threads are dispensed in two sets of warp threads 20and 22, each passing under the back bars 24 and 26 to the harnesses 28and 30 whereby for convenience and compactness they are fed into theupper and lower sheds of the loom.

The two sets of warp threads pass over the glass bars.

32 and 34, then overthe sand roll 36 and about the pressure roll 38,from thence over the ribbon guide rod 40 to the ribbon beam 42 which isdriven by the friction drum 44 from the sand roll 36 through a chain andsprocket drive 46.

The present invention relates to an attachment which is operativelyinterposed between the glass bars 32, 34- and the sand roll 36; and toimprovements in the friction drive of the ribbon beam 42 from thefriction drum 44.

It will be understood that the warp threads are woven into narrowfabrics such as ribbons, Webbing, or other narrow fabrics between thebatten 14 and the glass bars 32, 34. From the glass bars the ribbonpasses through the attachment forming the principal subject matter ofthis invention to the sand roll 36, and thereafter is wound upon theribbon beam 42.

Referring next to Figure 1, it will be seen that the ribbon beam 42 isprovided with trunnions 48 which are journaled in notches 50 provided inthe upper ends of the levers 52. The latter, in turn, are pivoted, as at54, to support brackets 56 suitably secured upon the floor upon whichthe loom rests. Tension springs 58 are connected to the members 52 andto standard 60 to thereby yieldingly urge the spindle of the ribbon beam42 against an appropriate friction surface of the friction drum 44.

The latter is preferably driven at a very slightly greater surface speedthan that of the sand roll 36, by the sprocket chain drive 46, in orderto apply a slight tension to the ribbons, as the same are wound upon theribbon beam 42 by the frictional engagement of the drum 44 upon thesurface of the ribbons wound upon the spindle of the drum 42. 1

It will be observed that the friction drum 44 thus serves to maintain aneven tension for all of the ribbons wound in side-by-side relation uponthe ribbon beam 42, in the position shown in Figure 3. As shown in thisfigure, the series of ribbons 62 are wound in close sideby-side relationthus permitting even and uniform winding of the ribbons in a compactmanner, and at a uniform wound upon a single warp beam in each of theside by side rolls of ribbons.

It should be noted that by this arrangement the cus tomary loose coilingof the ribbon in boxes, as in prior conventional practice, whichnecessitates the subsequent winding of the ribbons upon spools or reels,as Well as a much greater provision of floor space for receiving theribbons after they pass over the driving roller 44, is obviated.

It should be here noted that the warp beams will be of sufficient lengthto accommodate any desired number of ribbons to be wound side-by-sideupon the same, and in order to accommodate different sizes of ribbons,as desired.

Referring next primarily to Figures 2, 5-7, it will be seen that thereis provided a transversely extending plate 70 provided at its upper endwith horizontally extending mounting brackets 72 whereby the plate maybe mounted upon the breast beam 12 of the loom in a suitable manner, andbelow the glass bars 32, 34. At evenly spaced intervals longitudinallyof the plate 70 there are provided a plurality of guide pins 74projecting laterally from the plate. These pins are disposed atappropriate intervals corresponding to the ribbon 62 passing over theglass bars 32, 34. It will be noted, however, that a somewhat greaterspace is provided between the two central pins 76 and 78, which permitthe central ribbon of a set of ribbons which are to be wound upon thesame warp beam, such as the ribbon 62a, see Fig. 2, to pass betweenthese guide pins.

Depending from the central portion of the plate 70 are a pair of arms 80and 82 which support in dependent relation a guide plate84 which may beintegrally connected with the arms 80, 82, or may be detachably securedthereto, as set forth hereinafter. The plate 84 is provided with aplurality of longitudinally spaced laterally extending ribbon guide pins86, the spacing between which is in accordance with the length of theparticular width of ribbon which is being produced upon the loom. Aswill be now readily apparent, the number of the guide pins 86 willcorrespond with the number of the guide pins 74, and the two centralguide pins 88 and 90 are spaced apart a distance suflicient to permitthe passage of the central ribbon 62a previously referred totherebetween, and also the two adjacent ribbons as will be apparent fromFigure 2.

While the spacing between and the actual position of the guide pins 74are relatively unimportant and subject to wide variation, the actualpositioning and spacing of the pins 86 is extremely important. As willbe apparent from the diagrammatic view of Fig. 5, any particular ribbon62 which passes over the glass bars 32 or 34 has the plane ofitssurfacetangent to the glass bar 34. How ever, as will be apparent from Figure10, the ribbon 62 or 62a, as the same pass over the glass bars 32 or 34,travel with their surfaces tangent to that of the glass bars. Theribbons, however, are then turned through 90 degrees in order that theirsurface may be now tangent to the guide pins 74 as the ribbons travelfrom thence towards the second set of guide pins 86. It will be observedthat the vertical medial plane through the ribbons 6201' 62a, asindicated by the line 92 in Figure 10, is tangent to the surface of thepins 74 about which the ribbon turns, in order that the tension may bealong the center line of the ribbon. t V

In a similar manner, as will be apparent from Fig. 2,

.the ribbons after passing about the second set of guide pins 86, areagain rotated through 90 degrees and then pass in close parallelside-by-side relation from the last set of guide pins onto the sandroller 36. It will therefore be observed that when the presentattachment is applied to a ribbon loom, the Weaving of the ribbons isexactly in accordance with previous practice, and the woven ribbons thenpass from the glass bars and to the first set of guide pins of theattachment in exactly the same relationship as in conventional looms.However, at this point the ribbons are brought more closely together sothat the selected number of ribbons to be wound upon a single ribbonbeam will be in close side-by-side juxtaposition, and yet wherein therewill be no tendency to pull a ribbon on a bias or other than along itsmedial line.

It will now be understood that the guide attachment assembly consistingof the plates 70 and 84 will be each arranged with its correspondingguide pins in an appropriate position to take different sizes ofribbons; and also to take a different number of ribbons and dispose themin side-by-side relation. When it is desired to change either the numberof the ribbons to be wound upon the warp beam or the width of theribbons, it will be necessary to replace the attachment with anotherhaving the appropriate spacing and number of the guide pins thereon.

It is possible, however, to provide a further guide attachment which maybe more readily adapted for use with different sizes and Widths ofribbons. For that purpose, the arrangement shown in Figures 8 and 9 maybe employed. In this arrangement, there is provided an upper guide plate94 having the horizontal mounting brackets 96 thereon, together with thefirst set of guide pins 98, corresponding to the respective members 79,72 and 74 of the preceding embodiment. However, in place of the arms and82, there are provided depending arms 100 which are welded or otherwisesecured to the back side of the plate 94, and which at their lower endshave detachably secured thereto as by fastening bolts 16?. theupstanding arms 104 of a replacement lower plate 106 having thereon thesecond set of guide pins 108. The plate 106 of pins 108 will, of course,correspond to the plate 84 and pins 86 of the preceding embodiment. inthis latter form it is therefore evident that the second set of guidepins may be readily replaced with a plate having a different spacing ofpins thereon in order to permit the weaving of ribbons of differentwidths.

Referring now to Figures 3 and 4, it will be seen that an increase inthe length of the ribbon beam, for receiving wider and/or a greaternumber of ribbons thereon will necessitate a variation in the length ofthe friction drum 44 in order to uniformly apply tension to the surfacesof the rolls of ribbons. For this purpose, either or both ends of thedrum 44 are provided with a series of interchangeable extension sleeves45 detachably secured by means of suitable bolts to the brackets 47. Ifdesired, the brackets could be carried by the extension sleeves.

The foregoing is considered as illustrative only of the principles ofthe invention. Further, since numerous modifications and changes willreadily occur to those skilled in the art, it is not desired to limitthe invention to the exact construction and operation shown anddescribed, and accordingly, all suitable modifications and equivalentsmay be resorted to, falling within the scope of the invention asclaimed.
